What exactly is the difference between Fast and High Accuracy? - number of samples? - resolution of the scan? - number of points in the point cloud - or maybe it’s just a preset for the Point cloud fusing tool to give more o less detailed point cloud? ---

Only for the POP 2 (the original POP doesn’t give you this choice), _High Accuracy_ is the 0.1mm pitch and _Fast_ is the original 0.3mm pitch. ---

Ok, so the scanning resolution then. Thanks 🙂 ---

Not so fast , the resolution depends of the meshing settings , in Revo Scan the maximum is 6 in Revo Studio the maximum is 7 what is 75% higher than 6 . However higher resolution don’t means you will get more details. Higher accuracy means how far the points are from each other , the maximum accuracy for cloud point is 0.1mm in the Fast mode the accuracy starts at maximum 0.3mm , some claims high accuracy can be even at 0.5mm as long you fuse the cloud point in Revo Studio or other programs as Revo Scan offers fusion at 0.1mm only . so this is about the Accuracy of the scanned model features / details to be exactly. So if you want more details , always scan using Higher Accuracy and fuse the cloud point and mesh it in Revo Studio. Remember to remove overlapped points before meshing it . ---

Exacly - I meant the resolution of the point cloud, not the generated mesh 🙂 ---

It is spatial resolution aka point cloud density aka point cloud accuracy , all means the same
